Final answer:
Pricing for additional items, like an egg added to a salad, is based on business decisions similar to the example of a coffee shop changing its pricing model to charge separately for coffee, creamer, and sweetener. Businesses determine add-on pricing based on factors like cost, demand, and desired profit margins.
Step-by-step explanation:
The cost for a customer to add an egg to a salad isn't given directly; however, we can discuss how businesses determine pricing for additional items using examples from different industries.
In the case of fish pricing, the price is $3.25 per pound and this is the amount that commercial buyers pay at the fishing docks, which is different from what consumers will pay in a grocery store due to markups that cover the retailer's expenses and profit margin.
Similarly, to understand the concept of pricing for additional items, let's take a look at the coffee shop scenario. Initially, the cup of coffee was priced at $3, inclusive of creamer and sweetener. But with the new pricing model, the coffee is now $2, creamer and sweetener are each an additional $1. So, if a customer wants a coffee with both, the total now comes to $4 instead of the original $3.
The principle is that businesses will sometimes separate components of a product to offer a base price and then charge extra for add-ons, which could be similar to adding an egg to a salad in a restaurant.
